I have a 16Gb iPhone 4 to sell. It is in perfect working order, with all accessories and box. I have always kept it in a case with screen protector. It's only flaw is a scratch to the metal ring around it near the charger socket (the case did not cover this bit). It even still has the original protective film on the back of the phone. It was actually replaced for a completely new unit by apple about 8 months ago.
It was bought in September 2010, and I bought apple care with it so it remains under warranty until September 2012. Serial number is 61118565A4S if you want to check it here: https://selfsolve.apple.com/agreementWarrantyDynamic.do
HOWEVER... As it was bought in the US it is SIM locked to AT&T, so it would either need to be:
b) Used in the US/with an AT&T sim card
c) It can be used with a Gevey pro SIM adapter Which I can also provide.
I was lucky enough to get a new phone over Xmas so no longer need this one. I would like to get about 500 swiss francs for it, but am open to negotiation/offers.
Please PM me as soon as possible if you are interested. I wanted to give nice forum people the chance to buy it before I use other methods, but I need to know ASAP if there is any interest..
Thanks, and happy holidays.
